Pilot's Guide
HEADING SELECT MODE (HDG)
NOTE: HDG mode is only available when the G5 is configured as a backup
in a G3X/G3X Touch system and the G5 is receiving magnetic heading data
from an ADAHRS unit.
Heading Select Mode is activated by pressing the HDG Key. Heading Select
Mode acquires and maintains the Selected Heading. The Selected Heading is shown
by a light blue bug on the HSI and in the box on the bottom right of the HSI.
Changing the selected heading:
1) Press the Knob to display the Menu.
2) Select Heading and use the Knob to change the Selected Heading.
Or:
Rotate the HDG Knob (GMC 307 only).
Activating heading mode:
Press the HDG Key on the GMC.
Holding the CWS Button (if equipped) and hand-flying the aircraft does not
change the Selected Heading. The autopilot guides the aircraft back to the
Selected Heading upon release of the CWS Button.
Turns are commanded in the same direction as Selected Heading Bug
movement, even if the Bug is turned more than 180˚ from the present heading
(e.g., a 270˚ turn to the right). However, Selected Heading changes of more
than 330˚ at a time result in turn reversals.
